Brief Summary:

This research study is studying a combination of HER2-directed therapies (trastuzumab and pertuzumab) and hormonal therapy as a treatment after surgery for hormone receptor positive breast cancer.

The study drugs involved in this study are:

  • A combination of trastuzumab and pertuzumab given as an injection under the skin (PHESGO)
  • Hormonal (endocrine) Treatment

Condition or disease Intervention/treatment Phase
HER2-positive Breast Cancer Invasive Carcinoma of the Breast Breast Cancer Node Negative Breast Cancer Micrometastasis Breast Cancer Hormone Receptor Positive Breast Cancer Combination Product: Pertuzumab+TRASTUZUMAB Drug: ADJUVANT ENDOCRINE THERAPY Phase 2

Detailed Description:

The research study procedures include screening for eligibility and study treatment including laboratory evaluations, physical exams, questionnaires, and follow up visits.

  • Participants will receive HER2-directed treatment for 1 year and hormonal therapy for approximately 5 years.
  • It is expected that about 375 people will take part in this research study.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug combination to learn whether the drug works in treating a specific disease. "Investigational" means that the drug combination is being studied.

The drugs trastuzumab and pertuzumab are both monoclonal antibodies, which are disease-fighting proteins made by cloned immune cells. The U.S. Food and Drug Administration (FDA) has approved trastuzumab, pertuzumab, and trastuzumab + pertuzumab subcutaneous fixed dose combination (PHESGO) as treatment for HER2 positive breast cancer. The FDA has also approved hormonal therapies as treatment for hormone receptor positive breast cancer.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • HER2-positive T1 histologically confirmed invasive carcinoma of the breast. Patients must have node-negative (N0) or micrometastases (N1mi) breast cancer according to the AJCC 8th edition anatomic staging table.

    • If the patient has had a negative sentinel node biopsy, then no further axillary dissection is required, and the patient is determined to be node-negative. Axillary nodes with single cells or tumor clusters ≤ 0.2 mm by either H&E or immunohistochemistry (IHC) will be considered node-negative.
    • Any axillary lymph node with tumor clusters between 0.02 and 0.2cm is considered a micrometastasis. Patients with a micrometastasis are eligible. An axillary dissection is not required to be performed in patients with a micrometastasis found by sentinel node evaluation. In cases where the specific pathologic size of lymph node involvement is subject to interpretation, the overall principal investigator will make the final determination as to eligibility. The investigator must document approval in the patient medical record.
    • Patients who have an area of T1aN0, ER+ (defined as ≥ 10%), HER2-negative cancer in either breast, in addition to their primary HER2 positive tumor, are eligible.
  • For unifocal disease, all invasive disease must have been tested for ER and PR (for multifocal disease, see below). Either ER or PR must be positive, defined as ER ≥10% or PR ≥10%. ER- and PR-assays should be performed by immunohistochemical methods according to the local institution standard protocol.
  • HER2-positive by ASCO CAP 2018 guidelines, confirmed by central testing. See Appendix I for ASCO CAP 2018 HER2 testing guidelines.

    • NOTE: DCIS components will not be counted in the determination of HER2 status
    • NOTE: HER-2 status must be confirmed to be positive by central review prior to patient starting protocol therapy. Patients previously having had HER2 testing by NeoGenomics do not need to undergo retesting for central confirmation of HER2 status. A pathology report documenting testing by NeoGenomics should be provided at time of patient registration.
  • Bilateral breast cancers that individually meet eligibility criteria are allowed.
  • Patients with multifocal or multicentric disease are eligible as long as each tumor individually meets eligibility criteria, with the following exceptions: (1) central confirmation of HER2 status is needed only for any site of disease that is tested to be HER2-positive by local testing (unless original testing was done by NeoGenomics); (2) all areas that were locally tested for ER and PR status must be ER/PR positive (as defined above).
  • Patients with a history of ipsilateral DCIS are eligible as long as the patient has not received prior hormonal therapy. Patients with a history of contralateral DCIS are not eligible unless contralateral DCIS was diagnosed at least 15 years ago
  • ≤ 95 days between the date of protocol registration and the patient's most recent breast surgery for this breast cancer
  • Patients must have undergone definitive breast surgery for the current malignancy. All tumor should be removed by either a modified radical mastectomy or a segmental mastectomy (lumpectomy), with either a sentinel node biopsy or axillary dissection

    -- All margins should be clear of invasive cancer or DCIS (i.e. no tumor on ink). The local pathologist must document negative margins of resection in the pathology report. If all other margins are clear, a positive posterior (deep) margin is permitted, provided the surgeon documents that the excision was performed down to the pectoral fascia and all tumor has been removed. Likewise, if all other margins are clear, a positive anterior (superficial; abutting skin) margin is permitted provided the surgeon documents that all tumor has been removed. Radiation therapy to the conserved breast is required.

  • May have received up to 8 weeks of hormonal therapy as adjuvant treatment for this cancer. Patients should otherwise not have received prior hormonal therapy with the exception that hormonal therapy administered for less than 8-week duration at least 15 years ago is allowed.
  • Prior oophorectomy (including for cancer therapy) is allowed.
  • Patients undergoing breast conservation therapy (i.e. lumpectomy) must not have any contraindications to radiation therapy.
  • Patients who have participated in a window study (treatment with an investigational agent prior to surgery for ≤2 weeks) are eligible. Patients must have discontinued the investigational agent at least 14 days before participation in this study.
  • Men and women with any menopausal status ≥18 years of age
  • ECOG Performance Status 0 or 1
  • Participants must have normal organ and marrow function as defined below:

    • ANC ≥ 1000/mm3
    • hemoglobin ≥8 g/dl
    • platelets ≥ 75,000/mm3

    • Age ≥ 60 years
    • Age < 60 years with intact uterus and amenorrhoeic for ≥ 12 consecutive months prior to chemotherapy and/or endocrine therapy exposure (medication-induced amenorrhea is not acceptable to meet this criterion)
    • Age < 60 years hysterectomized and FSH and plasma estradiol levels in the postmenopausal range according to local policies prior to chemotherapy and/or endocrine therapy exposure.
  • Willingness to discontinue contraceptive hormonal therapy, e.g. birth control pills, prior to registration and while on study
  • Premenopausal patients with intact uterus must have a negative serum or urine pregnancy test, including women who have had a tubal ligation and women less than 12 months from their last menstrual period.
  • Women of childbearing potential and men with partners of childbearing potential must be willing to use one highly effective form of nonhormonal contraception or two effective forms of nonhormonal contraception by the patient and/or partner and continue its use for the duration of the study treatment and for 7 months after the last dose of antibody treatment and 3 months after the last dose of hormonal treatment.
  • Patients must be willing and able to sign informed consent.
